    Amazing, well built and powerful light. Assembly is easy and straight forward with clear videos walking you through step by step. Took 30 minutes and saved a lot with the DIY kit. Definitely worth the time. The light output and coverage is like no other. Just buy it. You’ll be so glad you did. I’m very satisfied and a customer for life!

    So far my plants have exploded after finally pulling the trigger on a beautiful ChilLED x3. I had to replace one of the bars after installing it but the customer service team was top notch! Had a replacement to me in 2 days, with a little gift on the inside! Will definitely buy more in the future. Great service 👏

    I have two of these kits and the quality is amazing. The kits are very easy to assemble. Two of these in my my 4×4 tent are pumping out the par. Now I need another for my 2×4 tent veg spectrum. Great product and company 👌

    Light shipped and arrived on time. Packaging was sufficient to keep the light protected and parts organized for easy assembly. It took me about 30 mins to assemble and power up. Everything in the box is quality.

    Once powered, this thing is bright. It’s a lot better than the cheap options out there. I will be purchasing another light and recommend to all my friends.

    I have had this light now for ~6 months and it is an amazing light. The build, finish, and performance is all top notch which makes me know that I am getting the best light for my money. The team is amazing with responses and is extremely helpful. Rest assured that this light is worth the money.

    I don’t think there has been better customer than this is that last 100 YEARS! Do not waste your time and money on crap that’s not made in the U.S.A. like Chilled Grow Lights are. Good luck trying to get someone to help you. You will jump out the window before then. The quality of the x3 is so good, that I plan on leaving this to my great grand children. This is a TANK.

    I’ve ran led for a while now currently I’m running this x3 side by side with a six quantum board 600 watt 48 volt and honestly the bigger light isn’t much brighter this lil 300 watt is showing it up with crisper clearer better looking spectrum, I’ve just hung the light recently but for now it’s thumbs up, now maybe chilLed can start thinking about good discounts on two or three units purchased together giving the home grower some motivation to make the switch?

    I’ve been running led for a while now in prior forms such as quantum boards and clearly with them still side by side in my grow these are far superior in spectrum and tuning as they are performing just as well as a six Qb 600 watt 48 volt meanwell ,mind you doing this with half the driver. So far this growers got two thumbs up ,good cool crisp light if I’m being honest tho your paying for the quality your getting I do wish they would produce these at a friendlier price or work on deep discounts when you buy 2-3 units something for the home grower to want to swap over or into chilLed.
